Javta roofing profiles: single- and three-layer 5-rib panels, Kliplock K400 and K450, SeamLock K1000 and the 4-rib PU/PIR panel — with tables of effective width, core thickness and density. The original drawings are coded by product width (K450, K500); the product pages use the effective-width code, which makes them K400 and K450.
